Abstract. The share of thermal energy in the total energy balance of rural areas is about 90%. A considerable amount of it is spent on the heat supply of the premises of livestock complexes. For example, breeding poultry under industrial conditions is characterized by a large concentration of poultry on the premises and involves the creation of bulky poultry complexes. This necessitates compliance with the special requirements for ensuring the required temperature regime in order to obtain high productivity of poultry at lower specific feed costs per unit of production. Due to poor temperature parameters in the poultry house, the potential productivity of the poultry is only 20-30% of the total productivity. There is an increase in metabolism, accompanied by an increase in feed costs. When breeding poultry meat breeds the deviation of the air temperature from the required value by only one degree leads to a marked decrease in the productivity of the poultry. Therefore, the task of modern systems of heat supply of poultry premises is to maintain the necessary temperature parameters in the location of poultry with quality control of air temperature as the poultry grows, which will significantly reduce energy consumption. The design of a local heating system, which is able to provide the necessary zoo hygienic requirements in the location of the poultry and a new way of growing poultry - modular poultry farming was proposed. With this method of keeping the poultry, the specified temperature conditions are created and a certain microclimate is required to ensure the zoo hygienic requirements with possible efficient and economical use of energy resources during economically justified period of normal operation. The paper justifies the feasibility of using energy-efficient technologies based on infrared radiation. Efficiency of application of the module for growing poultry with infrared radiator and forced ventilation system was confirmed. The field of influence of the exhaust outlet was studied and investigated under field conditions. It is established that the outlet operation does not affect the overall distribution of air flow in the module, since the radius of the suction torch is 0.16 m with a maximum exhaust air flow rate of 880 m3/h. Based on studies conducted on the efficiency of the exhaust outlet, it is found that the amount of heat recovered from the exhaust air is 30% of the heat output of the infrared heater.
Key words: infrared heater, exhaust outlet, suction torch, module for poultry breeding.
